Public Functions

Detailed Description

The QScriptable class provides access to the Qt Script environment from Qt C++ member functions.

With QScriptEngine::newQObject(), you can expose the signals and slots and properties of any QObject (or subclass) to script code. QScriptable augments this functionality by giving your C++ members access to the Qt Script environment they are invoked in; conceptually, it is similar to QObject::sender().

By subclassing QScriptable, you get the following functions in your class: thisObject(), argumentCount(), argument(), context() and engine(). With these functions, you have full access to the Qt Script environment from the slots and property access functions of your class, when they are invoked from script code.

For example, you can throw a Qt Script exception from a slot; manipulate the `this' object associated with the function call; inspect the arguments stored in the QScriptContext to know the "real" arguments passed to the function from script code; and call script functions from your slot.
